TECHNICAL FIELD

The present invention relates to method and system for providing an online game, and more particularly, to method and system which systematically maintain aggressive point information on a player character of a monster, and select a target for attack of the monster on the basis of the aggressive point information or distribute an experience point associated with the monster to a plurality of player characters.

BACKGROUND ART

An RPG (Role Playing Game) is a game in which a plurality of player characters meets with a monster as an example of various NPC (Non Player Characters) during a process for performing a particular quest, and obtains an item belonging to the monster, or increases its ability through a match with the monster, thereby performing the quest, while continuing a game together.

In this RPG, if a player character gives an attack to a monster, the monster reacts to the player character who has given the attack. At this time, in conventional online game providing method and system, to which player character a monster reacts first when a plurality of player characters attacks the monster, and the standard thereof are not clearly defined. Thus, since a monster reacts only to a player character that has performed an initial attack to the monster itself or the monster reacts without a regular rule whenever various player characters attack the monster itself, gamers' fun obtained through a game is reduced by half.

Also, in the conventional online game providing method and system such above, since a monster reacts only to a player character that has performed an initial attack, a “roundup of mobs”, that is, a particular expedient of an online RPG, was very popular among gamers.

The “roundup of mobs” is that one player character mobs and hunts down a plurality of monsters. In an online game according to the prior art, since monsters are densely distributed in a particular area where the roundup of mobs is advantageous, the systematic balance of a game collapses and gainers not using the roundup of mobs are lack of monsters to hunt down. However, the conventional online game providing method and system are not provided with appropriate apparatus capable of controlling the roundup of mobs.

Meanwhile, since the problems as described above reduce gamers' participation desire for a game, consequently profits of an online game company do not increase.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, online game providing method and system according to the present invention will be in detail described with reference to the accompanying drawings.

FIG. 1 is a network configuration diagram for explaining the schematic operations of an online game providing system according to the present invention.

An online game providing system 100 is connected to a terminal 115 of a gamer 110 and a communication network 120, and serves to provide game service to the gamer 110 via the online. In case that the gamer 110 who has installed a game-related program in the terminal 125 accesses the online game providing system 100, the game service may be provided through the game-related program run by game data or game patch transmitted to the terminal 125 by the online game providing system 100. The gamer 110 continues a game by using a player character controlled by the gamer 110 in the game environment.

The gamer 110 may be an internet user who has the terminal 115 to access the communication network 120 and receives predetermined game service by receiving game data or game patch to continue a game from the online game providing system 100 with which the gamer 110 is making a predetermined contract. Also, the gamer 110 controls motions of a player character to continue a game, and receives a monster band from the online game providing system 100 according to the motions of the player character.

The terminal 115 is a device that maintains a connection state with the online game providing system 100 through the communication network 120, such as the Internet and a telephone line, and embodies an online game while receiving data necessary to play a game from the online game providing system 100. That is, the terminal 125 is a general concept of terminals having computation capacity by mounting a predetermined memory unit and a micro processor, for example, a desktop personal computer, a notebook personal computer, a PDA (Personal Digital Assistant), a mobile communication terminal, and the like, and capable of accessing wired/wireless communication network.

FIG. 2 is a flowchart illustrating the process of generating aggressive point information and recording in a monster information database, in an online game providing method according to an embodiment of the present invention. The online game providing method according to the present invention is provided at a predetermined online game providing system.

In step 201, the online game providing system maintains an event database recording an aggressive point generation function corresponding to each predetermined event.

An event may include various types of acts received from a player character in accordance with inputting of a gamer in association with progress of an online game. Or, the event may include all changes and incidents in a game, satisfying a pre-set standard irrespective of a player character.

According to an embodiment of the present invention, there is provided a method for providing an online game, in which the event includes at least one of an attack trial event, an attack success event, a debuff trial event, and a debuff success event against the monster.

The attack trial event implies that a player character tries to cause damage to a monster through attack against the monster, the attack success event implies that a player character caused damage to a monster through attack against the monster, the debuff trial event implies that a player character tries to put a spell on a monster to weaken its ability, and the debuff success event implies that a player character put a spell on a monster to weaken its ability.

According to the present embodiment, certain aggressive point information about a player character is given, not only in case that the player character succeeds in attacking a monster, but also in case that the player character tries to attack. Also, debuff trial or debuff success of a player character against a monster is used as an element of aggressive point information. That is, since aggressive point information is generated through various acts of a player character, interests on a game get more and aggressive point information formed of a more reasonable numerical value may be generated.

Also, according to another embodiment of the present invention, the event may include a heal event or a buff event for another player character.

The heal event implies that a first player character cures a second player character, and the buff event implies that a first player character strengthens the ability of a second player character. Preferably, a monster that becomes to have aggressive point information with respect to the first player character by the heal event or the buff event may have aggressive point information with respect to the second player character before the heal event or buff event occurs. That is, in case that another player character cures a player character about which a monster has aggressive point information, or strengthens its ability, the monster becomes to have aggressive point information even with respect to the another player character.

According to the present embodiment, although a gamer does not input a direct act against a monster through his/her player character, in case that another player character about which the monster already has aggressive point information is cured or its ability is strengthened, certain aggressive point information with respect to the player character is given to the monster, interests of a game get more, and aggressive point information formed of a more reasonable numerical value may be generated.

Also, according to another embodiment of the present invention, the event may include an approach event within the predetermined distance of the visual field associated with a monster, or an attack success event against a player character from the monster.

In the approach event, it is regarded that a gamer may highly possibly attack a monster in case that the gamer approaches within the certain distance from the monster, although the gamer does not input an aggressive act against the monster through his/her player character. The attack success event from a monster has a meaning as a means to continue an attack although a player character does not react to the monster's attack.

As described above, according to the present invention, since various events in a game are involved in generating aggressive point information, the aggressive point information may be updated in real time, even while the game in progress. Further, since a target for attack of a monster is not fixed to one player character, but changed by a certain standard, there is an effect that the roundup of mobs is significantly prevented and interests of a game get more.

FIG. 3 is a view illustrating an example of an event database according to the present invention. In FIG. 3, an event identifier 301 is used to identify each event. One event corresponds to an event identifier, an aggressive point generation function, and a channel, and for example, a drawing symbol 302 shows that an “attack success” event corresponds to an identifier, “P2M_Damage”, an aggressive point generation function, “Function B”, and a channel, “Third channel”.

Like above, an aggressive point generation function corresponding to each event is recorded in an event database, and the aggressive point generation function may be pre-set by a game developer or a game provider providing an online game to meet the characteristics of each event.

Previously, it has been described about an embodiment in which the event includes an attack trial event, an attack success event, a debuff trial event, or a debuff success event against a monster. In the present embodiment, the aggressive point generation function may take a decrease rate of HP (Hit Point) of a monster according to receipt of the each event as at least one variable. The decrease rate of HP of a monster according to receipt of each event may be differential, and even in case of receiving the same type of events, a decrease degree of HP of the monster may be differential. Accordingly, a numerical value of aggressive point information may be different in accordance with the intensity of an event as well as the type thereof.

Also, previously, it has been described about an embodiment in which the event includes a heal event or buff event for another player character. In the present embodiment, the aggressive point generation function may take an increase rate of HP of said another player character as at least one variable. Or, the aggressive point generation point may take the level difference between a player character and a monster, the attribute of a monster, or an occupation of a player character as additional variable.

In step 202, the online game providing system according to the present invention receives a particular event from a player character or a gamer. The particular event may be at least one of the aforementioned events.

In step 203, the online game providing system identifies an aggressive point generation function corresponding to the particular event by referring to an event database. In step 204, the online game providing system generates aggressive point information according to receipt of the particular event on the basis of the identified aggressive point generation function. For example, referring to the drawing symbol 302, in case that the online game providing system receives an “attack success” event from a player character, the online game providing system may identify an aggressive point generation function, “Function B”, corresponding to the “attack success” event, and generate aggressive point information according to receipt of the “attack success” event in accordance with an aggressive point generation function, “Function B”.

In step 205, the online game providing system records the generated aggressive point information in a predetermined monster information database in association with the player character. FIG. 4 is a view illustrating an example of the monster information database.

Referring to FIG. 4, a monster of which a monster identifier is “M_id 0001” has aggressive point information with respect to a plurality of player characters including “suezo”, “windy”, etc. A monster of which a monster identifier is “M-id 0002” has aggressive point information with respect to a plurality of player characters including “karma”, “cluster”, etc.

According to an embodiment of the present invention, there is provided a method for providing an online game, in which the monster information database comprises at least one channel, an aggressive point is recorded in the channel for the each channel, and the aggressive point information is the total of aggressive points recorded in the each channel.

FIG. 4 illustrates an example of the monster information database comprising a first, a second, and a third channels according to the present embodiment. Referring to FIG. 4, the monster having the monster identifier “M_id 0001” records a first aggressive point, “50”, in the first channel, a second aggressive point, “25”, in the second channel, and a third aggressive point, “100”, in the third channel, respectively, and records the total of the first, the second, and the third aggressive points, “175”, as aggressive point information. Like above, if aggressive point information is maintained in the monster information database for each channel, it is possible to manage the aggressive point information more organically since the aggressive points change according to time on the basis of the peculiar characteristic of each channel.

According to an embodiment of the present invention, there is provided a method for providing an online game, in which a first aggressive point recorded in a first channel decreases in accordance with a first decreasing function of time, a second aggressive point recorded in a second channel decreases in accordance with a second decreasing function of time, and a third aggressive point recorded in a third channel is maintained to be regular, and a decrease rate of the first decreasing function is larger than that of the second decreasing function. The first decreasing function or the second decreasing function may change by a predetermined standard associated with progress of the online game.

In the present embodiment, a first channel is a channel where an aggressive point decreases fastest by time, a second channel is a channel where an aggressive point decreases slowly by time in comparison with the first channel, and a third channel is a channel where an aggressive point is maintained to be regular by time without decreasing.

In the meantime, according to an embodiment of the present invention, there is provided a method for providing an online game in which each event is recorded in an event database in association with the each channel. FIG. 3 illustrates an example of the event database recording each event in association with each channel.

According to the present invention, aggressive point information generated according to receipt of each event may decrease fast or slowly, or may be maintained to be regular without decreasing by connecting each event to each channel on the basis of the degree of decreasing an ability point of a monster. For example, if “A” event decreases an ability point of a monster by “10”, “B” event decreases the ability point of the monster by “50”, and “C” event decreases the ability point of the monster by “100”, the “A” event may be connected to the first channel, the “B” event connected to the second channel, and the “C” event connected to the third channel. That is, in case of an event causing huge damage to a monster, the monster may continue to attack a player character by maintaining aggressive point information by the event without decreasing. Also, in case of an event causing comparatively small damage to a monster, aggressive point information may be enabled to disappear by decreasing the aggressive point information fast or slowly according to time on the basis of the degree of the damage.

According to an embodiment of the present invention, there is provided a method for providing an online game in which, among the aforementioned events, the attack trial event and the debuff trial event are associated with the first channel, the heal event and the buff event are associated with the second channel, and the attack success event and the debuff success event are associated with the third channel.

Since the attack trial event and the debuff event cause comparatively small damage to a monster, it causes aggressive point information to decrease fast, and since the heal event and the buff event may cause big damage to a monster rather than the attack trial event and the debuff event, it causes aggressive point information to decrease a little slowly. Also, since the attack success event and the debuff success event may cause critical damage to a monster, aggressive point is maintained without decreasing. In this manner, aggressive point information may be maintained more systematically.

Like above, according to the present invention, there is an effect that it is possible to improve gamers' fun about a game by diversifying elements involved in generation of aggressive point information and influence according to each element. Also, according to the present invention, there is another effect that it is possible to enhance interests of a game through maintenance of more systematic aggressive point information by dividing the aggressive point information into various types and making disappearance of aggressive point information and a decrease rate thereof differential in accordance with each type.

Previously, procedures of generating aggressive point information and recording in a monster information database and various embodiments according to the procedures have been described. Hereinafter, an embodiment using the aggressive point information as above will be described.

FIG. 5 is a flowchart illustrating the process of determining a target for attack of a monster on the basis of aggressive point information, in an embodiment of the present invention.

In step 501, the online game providing system recording aggressive point information in a monster information database in association with a player character by performing the steps 201 to 205 extracts aggressive point information associated with a plurality of player characters from the monster information database. In this case, the online game providing system may extract aggressive point information associated with a plurality of player characters approaching within the predetermined distance of the visual field associated with a monster, in performing the step 501.

In step 502, the online game providing system determines a player character of which the extracted aggressive point information is largest among a plurality of the player characters to be a target for attack of a monster.

According to the present embodiment, there is an effect that it is possible to can prevent a roundup of mobs by systematically maintaining aggressive point information with respect to a player character of a monster and selecting a target for attack of the monster on the basis of the aggressive point information.

FIG. 6 is a flowchart illustrating the process of distributing an experience point associated with a monster to a plurality of player characters on the basis of aggressive point information, in another embodiment of the present invention.

In step 601, the online game providing system recording aggressive point information in a monster information database in association with a player character by performing the steps 201 to 205 extracts aggressive point information associated with a plurality of player characters from the monster information database. In this case, the online game providing system may extract aggressive point information associated with a plurality of player characters approaching within the predetermined distance of the visual field associated with a monster, in performing the step 601. Or, the online game providing system may extract aggressive point information associated with a plurality of player characters participating in a final attack associated with the disappearance of a monster.

In step 602, the online game providing system distributes the experience point to a plurality of the player characters according to the ratio of the each aggressive point information for the total of the extracted aggressive point information.

According to the present embodiment like above, there is an effect that it is possible to distribute experience points reasonably enough to satisfy garners by systematically using aggressive point information with respect to a player character of a monster and fairly distributing experience points associated with the monster to a plurality of player characters on the basis of the aggressive point information.

FIG. 7 is a flowchart illustrating the process of connecting a drop item associated with a monster with a particular player character on the basis of aggressive point information, in another embodiment of the present invention.

In step 701, the online game providing system recording aggressive point information in a monster information database in association with a player character by performing the steps 201 to 205 extracts aggressive point information associated with a plurality of player characters from the monster information database. In this case, the online game providing system may extract aggressive point information associated with a plurality of player characters approaching within the predetermined distance of the visual field associated with a monster, in performing the step 701. Or, the online game providing system may extract aggressive point information associated with a plurality of player characters participating in a final attack associated with the disappearance with a monster.

In step 702, the online game providing system connects the drop item with the particular player character of which the extracted aggressive point information is largest among a plurality of the player characters.

According to the present embodiment, there is an effect that it is possible to solve complications between gamers about possession of a drop item and remove gamers' distrusts about a game company by systematically using aggressive point information with respect to a player character of a monster and having a particular player character possess a drop item associated with the monster on the basis of the aggressive point information.

According to an embodiment of the present invention, in an embodiment distributing the experience point and an embodiment determining possession of a drop item, there is provided a method for providing an online game in which an event received from a player character includes at least one of an initial attack event, a final attack event, an attack success event, and a debuff success event against the monster, and a heal event and a buff event for a second player character.

In this case, the initial attack event may be associated with a channel where an aggressive point decreases in accordance with a predetermined decreasing function of time, and the final attack event, the attack success event, the debuff success event, the heal event, and the buff event may be associated with a channel where an aggressive point is maintained to be regular without decreasing.

According to the present invention, it is possible to improve a gamer's fun about a game by diversifying elements involved in generation of aggressive point information and the influence according to each element. Also, it is possible to distribute an experience point and solve a problem about possession of a drop item in a reasonable manner through the more systematic maintenance of aggressive point information by dividing aggressive point information into various elements and making disappearance of aggressive point information and a decrease rate thereof differential in accordance with each type.
